Yeah, homebrewing really pulls you in and doesn't let go. But I don't think so much about ingredients as I think, "Hmm, that would make an excellent mash tun," everywhere I friggin go. I'm pretty sure my girlfriend is sick of it.
Having background knowledge from homebrewing is nice too. Practically half of my plant biology exam was about the biochemical pathways of fermentation. Glycolysis FTW!
